SPECIFICATION forming part of Letters Patent No. 730,797, dated June 9,1903.

Application filed November 24, 1902. Serial No. 132,647. (No model.)

To all whom it may concern.-

Be it known that I, HENRY RENTSCH, of th city of Bacon, Moniteau county,State of Missouri, have invented certain new and useful Improvements inFurrow Opener Attachments for Corn-Planters, of which the following is afull, clear, and exact description, reference being bad to theaccompanying drawings, forming a part hereof. V

The object of my invention is to construct an improved furrow-opener forcorn-planters consisting in the novel features hereinafter shown,described, and claimed.

Figure 1 is a side elevation of a corn-planter, showing my inventionapplied to same. Fig. 2 is a top plan view. Fig. 3 is a detail view ofthe disk-carrying standards and the portion to which they are attached.Fig. 4 is a perspective view of my invention.

My present invention is designed as an improvement on Patents Nos.710,211 and 710,303, granted to me September 30, 1902.

Referring to the drawings in detail, 1 indicates the usual seed-chute orcasing, and 2 the runner or'fnrrow-opener, it being understood in thisconnection that I have only shown one side of the corn-planter and shownmy invention applied to only one side of the corn-planter, the remainingside of the cornplanter being done in the same manner.

3 indicates a transverse bar passing from one of the chutes to theother, and 4 indicates a similar transverse bar passing from the frontend ofone runner to the other runher 2.

5 indicates a clip having a square socket (5 and ends 7, provided withelongated open- 'ings S, and said clip is adapted to be boltedunderneath the transverse'bar 3.

9 indicates another clip provided with a square socket '10 and an end11, provided with an elongated opening 12, and said clip 9 is adapted tobe bolted on top of the transverse bar 4.

13 indicates a longitudinal angular rod which extends from the bar 3 tothe bar 4, the ends of said rod 13 being adapted to fit in the sockets 6and 10 of the clips 5 and 9.

By means of this construction the rod or bar- The clip 5 is adapted tobe'bolted underneath the transverse bar 3 by means of bolts 15. By meansof the elongated openings in the clips 5 and 9 they are laterallyadjustable in and out on the bars 3 and 4.

16 indicates one disk-carrying standard, and 17 the other. Saiddisk-carrying standards are provided with mating jaws or clampingportions 18, and formed in said mating jaws are square sockets 19. Therod 13 is made to fit into these sockets 19 when the jaws or matingportions 18 of the disk-carrying standards 16 and 17 are clamped andheld together by thebolt 20. Whenever said disk-carrying standards '16and 17 are secured to the bar 13, the said standards are prevented fromlateral movement, it being understood in this connection that byloosening the nut on the bolt 20 the standards may be adjusted in alongitudinal manner to the front or rear end of the rod 13.

- 21 indicates a tubular sleeve to which is attached the axle 22 onwhich the disk is mounted. Said sleeve 21 is vertically adjustable andis held in the desired adjustment by means of the set screws or bolts23.

From the foregoing description it can be seen that the front end of thebar 13 is mounted on top of the transverse bar 4 and the rear end ismounted underneath the transverse bar 3, and whenever the planter is inoperation there will be a rearward strain on the standards 16 and 17,which imparts to the front end of the bar 13 a downward pull and alsohas a tendency to produce an upward pull on the rear end of the bar 13.This arrangement produces a stronger and more efiective structure thanif both ends of the bar 13 were mounted on top of the transverse bars 3and 4.

Having fully described my invention,what I claim is 1. The improvedfurrow-opening attachment for corn-planters, comprising two paralleltransverse bars, the longitudinal rod 13 angular in cross-section, meansfor adj ustably securing the ends of the latter upon the said parallelbars, and a pair of furrow-opening disks supported by said longitudinalrod, substantially as specified.

2. The improved furrow-opening attachment for corn-planters, comprisingtwo parallel transverse bars, the longitudinal rod 13 angular incross-section,n1eans for adj ustably securing the ends of the latterupon the said parallel bars,adj ustable clips 5 and 9 provided withangular sockets, and a pair of furrowopening disks supported by saidlongitudinal rod, substantially as specified.

3. The improved furrow opening attachment for corn-planters, comprisingtwo parallel transverse bars, the longitudinal rod 13 angular incross-section, means for adj ustably securing the ends of the latterupon the said parallel bars, parallel disk-carrying standards 16 and 17provided with angular mating jaws having mating sockets and .adjustablysecured in position upon said angular rod, and disks mounted upon saidstandards, substantially as specified.

4. The combination with the transverse bars HENRY RENTSCH.
